怎样在textview中用handler循环自动更新里面的内容

例如private String conten[] = { "我是谁", "你又是谁", "他又是谁" };如何一直自动循环conten的内容

加个定时任务循环执行试试，每隔一段时间handler发送一个消息更新一下ui

 package test;

public class test {

    public static void main(String[] args) {
        String conten[] = { "我是谁", "你又是谁", "他又是谁" };
        int index = 0;
        while (true) {
            System.out.println(conten[index]);
            index++;
            if (index == conten.length) {
                index = 0;
            }
        }
    }

}

 String  content[] = { "我是谁", "你又是谁", "他又是谁" };
    private Handler hanlder = new Handler(){
        public void handleMessage(Message msg){
                updateText();
                hanlder.sendEmptyMessageDelayed(0, 200);
        }
    };

    private void updateText() {
        int i = 0; 
        if(i < content.length) {
            String currentString = content[i];
            i++;
        }
    }

调用：hanlder.sendEmptyMessage(0);
